取代基对苯甲酸酸性大小的影响

The Effect of Substituent Groups on the Acidity of Benzoic Acid

不同的取代基及同一取代基在不同位置对苯甲酸酸性大小的影响较复杂 .很多资料用诱导效应和共轭效应对一些情况作了解释 ,效果很好 .但还有许多情况下 ,用简单的诱导效应和共轭效应无法解释 .本文应用诱导效应 。

Different substituent groups and the same substituent group in different position have complicated effect on the acidity of benzoic acid. In this paper, we discuss the acidity of benzoic acid from the electron effect and neighbour effect.
